CORN-KNIFE.

SPECIFICATION forming part of Letters Patent No. 729,386, dated May 26, 1903. Application filed February'7, 1903- Serial No. 142,347. (No model.)

York, have invented certain new and useful 1 Improvements in Corn-Knives, of which the following is a specification. This invention relates to a knife adapted for removing corn's and the object of the invention is to provide a'safe, convenient, and durable device of this nature.

For this purpose the invention consists of a corn-knife comprising a handle, abladeseat arranged at the outer end of said handle, a blade secured to said seat, a U -shaped guard-plate over said blade, one leg of said U-shaped guard-plate being attached by a suitable thumb-screw to said blade-seat, and the other leg of said U-shaped guard-plate arranged beyond and slightly above the level of thecutting edge of the blade and extending parallel with the same.

The invention consists, further, in certain details of construction and combinations of parts, which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective View of my improved corn-knife. Fig. 2 is a top view of the same on a somewhat larger scale, 'a portion of the handle being broken away. Fig. 3 is a side elevation of Fig. 2. Fig. at is a side elevationshowing the parts in Fig. 3 Wl'tlIGXCG-PlilOll of the knife, guard-plate, and thumb-screw, which are here removed. Fig. 5 is a top view of the parts shown in Fig. 4. Fig. 6 is a vertical transverse section, on a larger scale, on line 6 6, Fig. 2. Fig. 7 is a plan View of the guardplate, and Fig. 8 is a plan view of the blade.

' Similar letters of reference indicate corresponding parts.

Referring tothe drawings, A indicates the handle of my improved corn-knife, the upper portion a of which is composed of wood, indiarubber, or othens'uitable material and the lower portion a of any suitable metal. The handle is provided at its outer end with a blade-seat a arranged, preferably, at an obtuse angle with the handle, as shown, said outer orrear corner the blade B is provided with a recess b At the lower portion of the handle cfl-f-i. c, at the junction of the same with the b1ade-seatis provided a shoulder or lug 5 adapted to enter recess b D indicates the U-shaped guard-plate, one le'gd of which is provided with three openings d d3 d The openings d d rec'eive the heads of the screws b, which heads thereby serve, in connection with a shoulder a between the lower end of the handle and the blade-seat, and a thumb-screw d, to secure the blade against shifting on the blade-seat. The guard-plate is retained upon the upper face of the blade-seat aiwith its open end outermost, by means of a thumb-screw 01 which passes through the opening 61 in the guard and into a tapped opening d in the blade seat. The guard-plate D is of such form thatits .outer. leg 6 is located laterally beyond the cutting edge e of the blade, as shown in Fig: 2, slightly above the level of I said cutting edge, as shown in-Fig. 6, thereby forming a guard-finger.

When using the device, the guard-finger e is rested directly upon the skin, and the blade then cuts at a slight level below the same. Oyving tothe guard-finger, the blade cannot cut into the flesh, but cuts off a thin layer from the corn. The portions cut off pass up between the guard-finger d and the edge e into the space between the finger c and leg (1 of the guard-plate, and, resting'on the knifeblade, may be readily lifted and discharged. The openings Z) d d are in the form of slots extending laterally of the blade-seat and guard, so as to permit the adjustment of the blade laterally toward or from the guardfinger e. The outer end of the blade B. projects somewhat beyond the leg or guard-finger e, and the outer end of the latter is-rounded off, as indicated in Fig. 2. This construction is for the purpose of facilitating the cutting out of the corn itself. \Vhen used for this purpose, the rounded outer end of the leg 0 is rested upon the skin adjacent to the corn, and the device then moved so that the outer end of the blade cuts circularly about the corn, thereby removing the same, while said guard-finger e prevents the too deep cutting in of the blade.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A corn-knife, consisting of a handle, a blade-seat at the lower end of said handle, a blade connected with said seat, and a U- shaped guard-plate secured to said seat, the outer leg of said guard-plate forming a guardfinger arranged beyond and slightly above, and extending parallel with, the cutting edge of said blade, substantially as set forth.

2. A corn-knife, consisting of a handle, a blade-scat at the lower end of said handle, and extending at an angle therefrom, a blade connected with said seat, and a U-shaped guard-plate secured to said seat, the outer leg of said guard-plate arranged beyond and slightly above, and extending parallel with the edge of the blade, substantially as set forth.

3. A corn-knife, consisting of a handle, a blade-seat at the lower end of the same, a shoulder between said handle and blade-seat at the upper side of the latter, a blade secured at the lower side of said blade-seat, and a guard-plate secured at the upper side of said blade-seat and abutting against said shoulder, substantially as set forth.

a. A corn-knife, consisting of a handle, a blade-seat at the lower end of said handle, a lug or shoulder at the lower side of said bladeseat, a blade at the lower side of said bladeseat and provided with a recess adapted to engage said shoulder, a lug or shoulder at the upper side of said blade-seat between the same and the handle, and a guard-plate secured to said blade-seat at its upper side and engaging said latter shoulder, substantially as set forth.

5. A corn-knife, consisting of a handle, a blade-seat at the lower end of said handle, a blade, screws passing through said blade-seat and securing said blade in position at the lower side of the same, a guard-plate at the upper side of said blade-seat, having a guardfinger extending parallel with the blade, adj acent the cutting edge of the same, and a thumb-screw passing through said guardplate into said blade-seat and blade, for securing said guard-plate in place, substantially as set forth.
